QIHG-Vertical Chemical Pump


Description for QIHG Vertical Chemical Pump
QIH type motor drive chemical pump designed for transferring chemical liquid, oil, petrochemical industry, metallurgy, light industry, printing dyeing, pharmaceutics, environment protect, seawater desalt, paper making, food and etc.industrial departments to transport corrosive medium without suspended grain or medium.
(1) The pump restricting parts adopt the advanced flow simulation technology to guarantee the reliable pump design
and the high operating efficiency.
(2) The anti-corrosion & anti-wear metal and rubber materials which are specifically developed for FGD pumps have been proved by the practice that, they can ensure the long-life pump operation. Through adjusting the bearing components to change the impeller position in the pump chamber all-time high-efficient operation of the pump can be achieved. The pump is characterized by the back knock-down structure which is simple and advanced.
(3) It is easy to maintain and repair and it is on need dismantling inlet and outlet water pipes. The containerized mechanical seal specially used for the desulfurization process is adopted and its operation is reliable.
The Feature for QIHG Vertical Chemical Pump
QIG pump inlet and outlet are given the same diameter and located on the same centerline.Impeller directly mounted on the extended shaft of motor to feature short axial dimensions and compact structure. It is easy to install and maintenance, with no need to dismantle the pipeline system.
1.Vertical structure, inlet and outlet given the same diameter and located on the same centerline, to be mounted in pipeline in the way as a valve, compact and smart appearance, little floor space required, low construction cost, and to be used outdoors if provided with a protective cover.
2. Impeller directly mounted on the extended shaft of motor to feature short axial dimensions and compact structure. Pump and motor bearings reasonably configured to effectively balance the radial and axial load in service, thus to ensure smooth operation with little vibration and low noise.
3. Use of mechanical seal or mechanical seal combination for shaft seal, sealing ring made of imported titanium alloy, medium-sized high temperature resistant mechanical seal, and wear resisting seal made of hard alloy to effectively lengthen the service life of mechanical seal.
4. Easy installation and maintenance, with no need to dismantle the pipeline system. And all the rotor parts may be taken out only by taking off the nuts on pump union base.
Application for QIHG Vertical Chemical Pump
It can be used for transporting corrosive liquid in industry of steel plant ,power plant, coal industry, desulfurization circulation system, water treatment, chemical process, non-ferrous metal smelting industry, sulfuric acid phosphate fertilizer industry.
